[theme-reviewers] Theme Unit Test XML file fixed

[Lance Willett]

Hi reviewers,
New version of the Theme Unit Test XML file is ready for use. The
previous version had a malformed XML tag that was causing a few issues
in the import process.

Thanks to Mel (esmi), Jon Cave (duck_) and Kim Dobson for reports and
helpful info to track it down.

Cheers,
Lance
